I am repairing a TK-80 for a HAM Friend. The radio is flawless in rx mode. However, when trying to tx, the radio displays the message "POWER" and shuts down. What is wrong with this radio? 73

Specifications say it wants 20.5amps at 13.6 volts DC. If the power supply is not capable of supplying at least that, it's going to behave like what you are seeing.
